3 YEAR EXTENDED WARRANTY SCHEME

The product price includes a one year warranty and 30 day money back guarantee.

However, the Gear4music extended warranty scheme provides an enhanced service, and is designed to offer a higher level of protection than many 'free' warranties offered by some retailers and manufacturers.

The highlights of this enhanced warranty service are:

  • Warranty is extended to 3 years from the date of delivery.
  • Our Money Back guarantee is extended from 30 days to 60 days (terms apply after 30 days)
  • Collection and delivery costs are included for the first two years
  • Claim 50% cash back on the cost of the policy after 3 years if it has not been used!
  • Warranty is transferable if the item is re-sold
  • Loan or replacement equipment will be provided if the product isn't repaired within 30 days
  • If an item can not be repaired, a similar alternative product or cash discount (as defined in this policy) will be offered
  • The policy can be cancelled within 30 days, and at any time after that for a pro-rata discount

Please note that this extended warranty is currently only available on products sold within the EU or EEA, and is subject to the terms and conditions as detailed on the extended warranty certificate provided.

For customers in outlying areas of the country, the price of the Extended Warranty may be marginally higher, due to the potential for higher collection and redelivery transport costs.

This enhanced warranty is in addition to the standard Gear4music and manufacturer warranty policies, and the Gear4music terms and conditions of trade. No statement or condition of sale contained within these terms affects or restricts your statutory rights as defined under the Consumer Contracts Regulation 2014.

API 550B Discrete 4 Band EQ

Details
The API 550b Discrete 4 Band EQ is based on API's original 550 model from the late 60's. The 550b follows on from its parent model introducing an additional filter band and several new frequencies. Inside the 550b is API's exclusive circuitry and components, such as the API 2520 Op-Amplifier for high quality sound production. The four EQ bands offer seven switchable filter frequencies that span over four-to-five octaves, hand picked from some of the industry's most revered engineers. The ''Proportional Q'' design is also featured in this unit, widening the filter bandwidth at low settings and narrowing it at higher setting, eliminating the need for additional bandwidth controls. The quality components and long lasting design aspect make this 4 band EQ ideal for console installations.

''Proportional Q'' Control

Saul Walker (The founder of API) designed the ''Proportional Q'' control in the '60s, allowing for the widening of the filter bandwidth at minimal settings whilst narrowing it at higher settings, without the need for additional bandwidth controls. This feature helps to minimise the phase-shift sound found in many equalizer units.

Based On The Classic 550

The 550b is based on the API's original 550 developed in the late '60's. The original 550 played a pivotal role in the history of music recording, being a prominent fixture in many recording studios. The API 550b is an updated version of the classic EQ, with an additional filter band and several new frequencies, hand-picked by the industry's finest sound engineers.

The API 500 Series

The API 500 Series focuses on high sound quality and longevity at an affordable price range. Considering most studio rigs undergo a large amount of swapping and changing between equipment, the API 500 series is designed to last, from its high quality components down to its rugged and durable design.
